If this is true, and they really are considering a GMR refresh along with this, why not just do all Disney movies, which now could include Pixar, LucasFilm, and maybe even some of the Marvel movies, depending on how they did them. Although, I think the Marvel characters and their images are restricted from appearing in WDW due to Uni's contract. Still though, even without Marvel, they would have a pretty impressive roster of films to pick from, without having to go out of house. Heck, they might could even get Cameron to agree to them use his films as well.
